Can you imagine driving your car across America without ever turning off its engine? The prospect of this technology is not as far-fetched as you may think.

Limnia, an energy solutions company that has recently secured a patent for storing hydrogen as a solid, announced that it was preparing a new product for volume factory manufacturing. Dubbed AutoPack, the device incorporates a hybrid fuel cell and battery array with an energy computer and Limnia's patented fuel cassettes in what may be longest range vehicle energy system in the market.

The company says that the new technology will deliver the lowest cost per trip, longest range, safest, most upgradeable power plant for electric and hybrid vehicles. I wonder which EV maker will jump on the AutoPack first.
